To all 'z vwm it may concern.

Be 1t known that we, HENRY A. WISE WOOD and JOHN A. llsBELL, citizens of the lUnited States, said WOOD residing at New York, county and State of New York, said 'lfsBELL residmg at Middletown, in the county of Orange and State of New York, have invented a new and useful Pulsating-Ean Delivery, of which the following is a speci cation.

. This invention relates to folding machines for delivering the product in separated or folded sheets and particularly to the class of folding machines usually used in connection with web printing presses.

The principal objects of the invention are to provide improved means for directing a multiplicity of folded sheets first in one direction and then a multiplicity of folded sheets in another direction, and means cooperating therewith for automatically assembling the two bundles of predetermined numbers of sheets in one pile with their folded edges facing in opposite directions.

Further objects and 'advantages of this invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which- Figure 1 is a front elevation of a preferred embodiment of the invention;

, theshaftsaa and 2:3 rpspeetivey.

The machine is shown as comprising a frame'lO which supports the main driving shaft 11. Through gearing this shaft drives a gear 12 which in turn drives a gear 13, a folding cylinder 14 and a cutting cylinder 15. These parts can be arranged in any suitable way to deliver folded sheets between guides 16 and 17. The gear 12 drives a similar gear 12a and all the mechanism hereinbefore -and hereinafter described as being driven from the gear 12 is duplicated on the other side of the machine, preferably, and driven in the same way by the gear 12a.

Un the shaft with the gear 13 is a gear 18 driving a gear 19 and through that a gear 20. The gear 20 drives a gear 21 of the same size. The gears 20 and 21 are on two shafts 22 and 23 respectively, these shafts being similar and being hereinafter designated as the lower and upper fan shafts respectively. These two shafts rotate at the same speed in opposite directions. The shaft 22 is used for driving several of the mechanisms to be described hereinafter, and can be considered as an intermediate driving shaft.

Through two pairs of worm and spiral gears 24: the shaft 22 drives a cam shaft 25. On this shaft is located a grooved cam 26 which operatesa roller 27 on an arm 28 projecting from an oscillating lever shaft 29. This shaft extends past the two shafts 22 and 23 and is provided with pairs of fingers 30 on opposite sides thereof. Each of these pairs of fingers engages between the flanges of a collar 31. One of these collars is located slidably on the shaft 22 and the other on the shaft 23. The two sets of fingers are so located that when one of these collars is moved to the right the other will be moved to the left. Each yof these collars is `provided with a preferably cylindrical. extension 33 having yangular teeth on. its outer surface. lt will be understood that while these members 31 and33 are movable together alongthe shafts on ywhich they are located, they areconnected with them by a sliding spline. in a groove 34 in each` shaftf` Ofgshaft 36 journaledin members 37 .fiid

each of these shafts 36 vare a vseries of fan blades 38.

From what has been said it will be seen y that as the cam 26 revolves it gives a forward and backward lateral motion to the sleeves 31. Through the angular teeth thereon, the shaft 36 causes the fan blades on one of the shafts 22 or 23 to be extended while those on the other of these two shafts are withdrawn, these fan blades of course having simply an oscillating motion on the shafts 36. Therefore, the parts so far described are so designed that when a given number of sheets have been delivered through the lower fan on the shaft 22 the lower fan blades are withdrawn from the guides 16 and 17. The blades on the upper fan shaft 23 are simultaneously and automatically extended into the path of the sheets between these guides, and then a similar number of sheets having been delivered to the upper fan kthe reverse action takes place. h

A cushioning device is shown in Fig. 5. An eccentric 39 on the cam shaft 25 has a vstrap 40 provided with an adjustable rod 41. On this is a double spring 42 between the two parts of which is swiveled the end of an arm 43. This arm is pivoted 0n ya stud 44 and has another arm 45 entering a space between two lugs 46 on the oscillating lever shaft 29. When the roll 27 shifts in the cam groove the eccentric 39 has just been shifted so that one half of the spring 42 is under compression. This softens the shock given to the parts operated by the cam 26.

On the shaft 25 is located a lowering cam 47. On this cam work two rollers 48 and 49.

One of these .rollers is mounted on a pivoted lever 50, and connected byva link 51 with the bottom lowering arms 52. The top lo w ering arms 5.21 are operated from the other roll similarly. The cam 47 is so designed that when the lower fan blades are withdrawn to the bottom lowering arms 52 are in position to receive the pile of 'folded sheets therefrom and to lower them to the full line position shown in Fig. 1. The same conditions prevail with the upper lowering arms as will appear hereinafter.

Also located on the shaft 25 is a stop cam 53 operating a roll 54 on a lever 55 connected by a link 56 with a lever 57 which in turn operates a stop 58 to withdraw it upwardly out of the way of the advancing bundles when they are removed from the lowering arms in a manner to be described hereinafter. Guide 17 has a fixed stop 59.v

A shaft 60, on which the gearing 24 is l0- cated, extends downwardly and is provided with a gear 61 near the bottom of the frame which in turn operates a conveyer through gearing 62. This conveyer comprises two pairs of sprocket wheels 63 for an endless chain 64. The cross pieces 65 with which this double chain is provided have transverse (vertical) pushing arms 66. These are kept in vertical position by providing a pair of hubs 67 horizontally eccentric with respect to the sprocket wheels 63 and having teeth 68 thereon for an endless chain 69. This chain is'connected by a horizontal link 70 with the chain 64. This link is made horizontal at all times by connecting it up in that way and making its length equal to the eccentricity of the hubs 67. In this way the chain 64 is kept always in the same relative position with respect to the chain 69 and the cross pieces are also incapable of turning on their own axes as they travel in their orbit. In this way the arms 66 are kept in vertical position. f,

The operation from the point at which the bundles are delivered by the fan to the lowering arms 52 and 53 is as follows First the lower arms 52 are lowered to a point just above the table guides and the upper arms 53 are raised. Then the pushing arms 66 push the bundle of folded sheets from the arms 52 on the table guides 71 and advance to the position 66A.

When the pushing arms 66 reach the dotted line position indicated' by 66A an up-l per bundle is completed and the fan blades are reversed. Thus the sheets are redirected 95 to the bottom lowering arms 52, and the stop 58 is made to rise out of the way of the advancing bundles so that the bundle lresting on the upper lowering arms is delivere on top of the bundle on the lower lowering arms. Both are delivered together in reverse position on the fingers 72 of an elevator or stacker 73 as shown in Figs. 1, 2 and 12. This elevator as shown receives bundles of folded sheets in its alternate spaces, from two delivering mechanisms. Each set of fingers is loosely pivoted on a rod 74 and has a projection 75 normally engaging under a fixed stop 76 projecting from the rod. This holds the lingers horizontal until they pass over at the top and then limits their reversal.

It will be seen therefore, that a comparatively simple mechanism is provided for accomplishing these results and that it is of such a nature that it can be timed readily so that the several `motions will take place in proper order and it is practically impossible to get it out of order in ordinary practice because all the motions are positive.
